The Canadian University Society for Intercollegiate Debate (CUSID) is a national organization which governs and represents university debating in Canada. We sanction several official tournaments, including the various regional championships, the British Parliamentary Championships, the National Championships, and the North American Championships in conjunction with the American Parliamentary Debate Assocation. Our membership is comprised of debating clubs, sanctioned by their respective universities, from across Canada.

As the Société Universitaire Canadienne pour le Débat Intercollegial (SUCDI), we also promote and facilitate french language debate at the university level, including hosting the Compétitions Nationales Françaises (CUSID French Nationals).
